Ok, so I'm assuming you are in Australia, the UK or perhaps India based on the use of the word boot and the model TV. I am not at all familiar with that TV. I believe the Wisdom Share Smart Cloud TVs run on Android. You can try to replicate the issue of the audio not coming on again. If it does not work while streaming something, go into the TV menus and see if there is a setting to change the output of the audio from the receiver to the TV speakers. If you can get the sound out of the TV, switch it back to the receiver and see if it works. If not, check for a firmware update and run it to see if it addresses the issue. If your TV has an optical or coaxial audio output, you can use it to connect to the Denon and not use the ARC feature. This will result in audio being capped at DD 5.1 and DD+ signals will not be output from the TV. I do not believe you would hear a difference. You should not experience the audio drop outs if you connect the TV to the Denon using either the coaxial or optical connections. I hope you can sort it out.
